Built for Chevy and GMC 3/4-ton truck owners who want a level stance with serious tire clearance, this 4-inch lift kit raises your front end to match the rear, delivering a factory-like ride quality even at height. You'll gain the ground clearance to fit 33"–35" tires and the aggressive appearance that sets your classic truck apart.

What's included

• Front lifted leaf springs (pair) — Raise the front end 4 inches while maintaining ride quality and factory geometry.
• Rear lifted leaf springs (pair) — Keep your truck level front-to-back and preserve the suspension's natural compliance.
• Raised steering arm — Corrects caster and steering geometry after the lift to maintain proper wheel alignment and drivability.
• N3 shock absorbers (pair) — Rough Country's 10-stage variable nitrogen-charged shocks deliver smooth highway performance and off-road control, with a durable 18mm piston rod and fast-cooling 54mm body.
• Brake line relocation brackets — Keep brake lines at safe angles and prevent stretching or damage during suspension articulation.
• U-bolts and hardware — Everything needed to secure springs and components to your frame.

Important notes

• This kit ONLY fits models equipped with 56-inch rear leaf springs. Verify your truck's spring length before ordering.
• If your vehicle has a factory front sway bar, drop brackets (SKU: 1019) are recommended to maintain proper suspension geometry and prevent binding.
• Vehicles with factory quad shocks (two front shocks per side) will use a single aftermarket shock per side in this kit.
• Proper wheel backspacing is critical to avoid suspension interference; confirm your wheel specifications before installation.
